Abbreviations: AED, antiepilepsy drugs; BX, biopsy; CP, complex partial; Front, frontal; GTC, generalized tonic clonic; GTR, gross total resection; HH, homonymous hemianopia; NA, not available; NED, no evidence of disease; NTR, near-total resection; Occ, occipital; Par, parietal; QA, quadrantanopia; SD, stable disease; Sens, sensory; SP, simple parietal; STR, subtotal resection; Temp, temporal; VF, visual field.

^aThe patient was seizure-free for 4 years, then seizures recurred and progressed during the next 8 years until a second resection was performed because of radiologic progression.

^bThe patient underwent biopsy, and after 10 days, definite surgery. Five months later, the patient developed seizures, but the MRI was negative for a tumor. Approximately 4 years later, surgery was performed on the epileptic focus; no tumor was found.

^cThe patient was blind in one eye because of congenital glaucoma and had QA in the other eye.

^dThe visual field test used was a confrontational test administered by a neurologist.

^eThe diagnosis of absence seizure was based on retrospective history from family and patients that was taken after the surgery; no EEG was performed to confirm.

^fThe patient failed 11 different AED until the second surgery, where he needed only 2 AED after second surgery for 2 years and was able to stop AED without recurrence of seizures.

^gThe patient had CT shortly after surgery and it showed a a mass, but the family deferred surgery for 5 years.

^hThe duration from seizure to surgery in this patient was only 2 weeks.

ⁱThe patient died from a cause not related to his disease after last contact.
